SOAP-MANUFACTURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 332,605, dated December15, 1885.

Application filed August '7, 1885. Serial No. 173,804. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. GRANT, a citizen of the United States,residing in the city of Houston, county of Harris, State of Texas, haveinvented a new and useful Improvement in Soap-Manufacturing Machines,which improvement is fully set forth in the following specification andaccompanying drawings.

Figure 1 represents a side elevation, partly sectional, of an apparatusembodying my invention. Fig. 2 represents asectional view of a portionof the device on line as 00, Fig. 1.

Similar letters of reference indicate corresponding parts in thedrawings and specification.

- herein is reserved and claimed in another application by applicant, ofeven date herewith, (August 7, 1885,) and bearing Serial No. 173,805.

Referring to the drawings, A represents a tank or charger, in which thevarious ingredients of which the soap is to be formed are placed. Thistank is placed in an elevated position, or above the rest of theapparatus, so that the solution can be readily conducted by gravity fromthe same through pipeB to the compressor 0.

In pipe B there is a valve or cut-off, B, whereby the flow from thecharger can be checked or stopped when desired.

The compressor 0 is a cylinder composed of steel or other suitablematerial, having a body and detachable heads D, the latter being securedby bolts and screws to the said body, so that the said heads may beremoved when desired for cleansing or other purposes.

Grepresents supports or standards on which the compressor is placed.

Passing through one of the heads D is ashaft, E, having a stuffing-boxand carrying a pinion, E, on its inner end. Motion is communicated tothe said shaft by means of a bandwheel, D, thereon, which receivesmotion from any suitable motor.

Secured to heads D is a rigid shaft, G, which has mounted thereon aperforated sleeve, F, carrying a pinion, F, meshing with the pinion Bymeans of the perforations in the sleeve F the inner rigid shaft islubricated by the mixture in the cylinder. Rigidly secured to the sleeveF are blades H, which extend radially therefrom and are formed either ofmetal or wood, and are of any suitable shape.

\Vithin the compressor 0, and several inches from the wall thereof, isacoil of iron p pe, J, extending the entire length of the cylinder, oneend of which is connected to asteam-chest or generator, while the otherend, passing outside of the cylinder, has atrap connected therewith. Thecoil J is strengthened in its position by iron bars K,placed atintervals between the said coils J and the steel cylinder 0.

L represents a hydraulic pump, suitably connected with the compressor 0by the pipe L, having a cock at L for regulating or shut ting off thepressure.

M and N represent, respectively, an ordidinary pressure-gage andthermometer, O a

safety-valve, which may be of any usual construction. 4

The operation of the device is as follows: The mixture of which the soapis to be formed is placed in the charger A, and from thence conveyed bythe pipe B to the compressor 0. When the latter is nearly filled,theflow there in is stopped by means of the cock B, and the perforatedsleeve carrying the blades H is revolved at the rate of about thirtyrevolutions per minute, thoroughly mixing the mass,which is heated tothe temperature of at least 160 Fahrenheit, or higher, as may be needed,by means of steam injected through the coil J, which extends the entirelength of the cylinder. A pressure of from three hundred and twenty-fourto four hundred pounds per square inch, owing to the quality of thematerial, is then applied by means of the hydraulic pump L to themixture, when in about four or five minutes the soap is in propercondition for running into the molding-frames by means of theoutlet-pipes.

WVhat I claim, and desire to secure by Letters Patent, is-

1. Apparatus for soap manufacture,consisting of a charger, a compressor,having a mixer and heating-coil within the same, and a hydraulic pumpconnected to said compressor, all arranged and combined substantially asdescribed.

2. The charger A, in combination with pipe 13, having cock B, compressor0, having steamcoil J within the same, extending from end to endthereof, a rotary mixer Within the said compressor, and means,substantially as described, to rotate the same, and a hydraulic pump, L,connected to said compressor by pipe L, having cook L, substantially asdescribed.

3. The compressor 0, having detachable heads D, rigid shaft G, rotaryshaft E, having pinion E, means, substantially as described, to rotatethe said shaft E, perforated sleeve F, having pinion F, meshing with E,and blades H, substantially as described.
